Abstract
A TfOH-promoted tandem synthesis of 1,3-disubstituted naphthalenes is developed via a directed-aldol reaction and a Friedel-Crafts reaction. Two new C-C bonds and one new benzene ring are created efficiently in one pot due to the discovery of a TfOH-promoted highly chemoselective directed-aldol reaction between two different ketones with α-hydrogens.

Abstract
C-1 substituted tetrahydroisoquinolines have emerged as important scaffolds in
pharmaceutical and medical research. Although various methods for α-substitution on tetrahydroisoquinolines
have been discovered, the introduction of the azole group at C-1 position
remains a challenge. Recently, direct C-H activation methods and multicomponent reactions
have been employed towards the synthesis of azole containing tetrahydroisoquinolines. A
summary of such synthetic strategies is presented here as these promising methods can help
in developing more efficient synthetic routes. This minireview covers the available synthetic
methods and their mechanistic pathways for the preparation of C-1 azole substituted tetrahydroisoquinolines.

Abstract
Starting from the chiral 5,6,7,8-tetrahydroquinolin-8-ol core, a series of amino-phosphorus-based ligands was realized. The so-obtained amino-phosphine ligand (L1), amino-phosphinite (L2) and amino-phosphite (L3) were evaluated in iridium complexes together with the heterobiaryl diphosphines tetraMe-BITIOP (L4), Diophep (L5) and L6 and L7 ligands, characterized by mixed chirality. Their catalytic performance in the asymmetric hydrogenation (AH) of the model substrate 6,7-dimethoxy-1-phenyl-3,4-dihydroisoquinoline 1a led us to identify Ir-L4 and Ir-L5 catalysts as the most effective. The application of these catalytic systems to a library of differently substituted 1-aryl-3,4-dihydroisoquinolines afforded the corresponding products with variable enantioselective levels. The 4-nitrophenyl derivative 3b was obtained in a complete conversion and with an excellent 94% e.e. using Ir-L4, and a good 76% e.e. was achieved in the reduction of 2-nitrophenyl derivative 6a using Ir-L5.
